Absolute Encoder
Absolute encoders are position feedback devices that report absolute positional information. An absolute encoder generates a unique code for each position. Absolute encoders do not lose position when power is removed. Since each position is unique, true position verification is available as soon as power is up. It is not necessary to initialize the system by returning to home base.
- Nonmagnetic Absolute Encoder
These linear and rotary encoders have been tested in environments up to six Tesla and have no influence on the machine environment. The encoders can also withstand a high magnetic environment without loss of accuracy or resolution and are mechanically stable. Non-magnetic encoders are commonly found in MRI machines, as well as semiconductor and microscopy fields.
